Vasopressor Infusion Calculator

Calculate infusion rates for vasopressors (e.g., norepinephrine, dopamine) to manage blood pressure in critically ill patients.

Vasopressors are potent medications used in the ICU and ER to increase blood pressure and improve organ perfusion in patients with shock. Because these drugs have a very narrow therapeutic window and immediate physiological effects, they are almost always administered as continuous weight-based infusions (e.g., mcg/kg/min). Precision is vital, as small changes in the infusion rate can lead to significant changes in hemodynamics. This calculator helps clinicians bridge the gap between an ordered dose and the required pump setting in mL/hr, accounting for the drug's concentration in the IV bag and the patient's weight.

Typical units: mcg/kg/min

Result

26.25 mL/hr

Infusion rate: 26.25 mL/hr for ノルアドレナリン

Drug (label only)ノルアドレナリン
重量(kg)70 kg
Target dose7 mcg/min
Concentration16 mcg/mL

使い方

The tool calculates the concentration of the solution (Total mg / Total mL). It then uses the patient's weight and the target mcg/kg/min dose to determine the total micrograms per minute required. Finally, it converts this to milliliters per hour for pump programming.

計算式

Rate = (mcg/kg/min × kg × 60) / concentration

計算例

1. **Levophed**: 70kg at 0.1 mcg/kg/min (4mg/250mL) = **26.3 mL/hr**.
